Yes, it turns out that there was an error in the processing of one-row matrices using ans_array. I submitted a patch last week, and it is in the 2.7 release. The changes are in pg/lib/Value/AnswerCheckers.pm. I think you should be able to replace your current copy with this version without trouble (but save your earlier copy just in case).
